and 27 actuate the devices for'prodtpcing the springs by means of their cams 28 and 29, as will be shown below. On shaft 15 there is 'alsorigidly mounted the pinion 3 which transmits its rota i "-n by means of tits chain 31 to the pinion 2 of shaft Oh shaft 33 the gear-wheel 3A is rigidly i iouni: ed which gears with the gear-wheel 35 01 shaft 36. 'On shafts 33 and 36 (Fig. 3), the two feeding cams 37 and 38am rigidly mounted which are so formed that only one half of their periphery operates so as to eifect the feeding forward of the wire 39.

The Wheel 4-0 fixed to shaft 15 transmits by means of a chain 41its rotation to the wheel 42 on the shaft 43. Parallel to the shaft 43 is journaled the shaft 44 and the rotation of shaft 43 is transmitted to shaft 44 by means of the pinions 45 and 46. The cams 47 and 48 on the shafts 43 and 44 respectively are provided for actuating the devices which effect the inserting of the springs.

Each link of the conveyer band or chain is arranged to receive a group of press-buttons in which the springs are to be inserted. The number of press-buttons belonging to each group can be optionaL. In the present case, as best shown in Fig. 4, each frameshaped link is arranged to receive a group of five ress-buttons. These press-buttons 49 whi are to be provided with springs are, before the springs are inserted, of the form shown in Fig. 9 which is obtained by means of known stamping machingf.

As can be seen from Fig. 9, v e pressbutton isof a hollow cylindrical form with a slightly convexed bottom, said bottom having at its center an upwardly directed domeshaped protuberance or map. This domeshaped protuberance or cap 72 is provided which are made from the wire 39, as will be e.\- lained later, are inserted.

e apertures 51 provided in the frame or link I serve to receive the press-buttons 49. Said'a ertures 51 are provided with oilpositely isposed recesses 52 (Fig. 4). ots 53 open into the apertures 51 and blocks 54 are slidably mounted by means of dovetails in the slots 53, saidblocks 54 being under the .action of springs 55. The sai springs tend to press the block 54 against the press-buttons and in this manner to hold the press-buttons securely in the apertures 51. The forward movement of the blocks is limited by pins 92 which engage in recesses 93 in the bloc The press-buttons 49 are placed in the apertures 51 in such a manner that their slots.50, 50' lie opposite the recesses 52.

The tool for forming the springs is arranged above the co'nveyer chain 1, and consists substantially of two members 57, 58 slidably mounted in a table 56, the ends of the members 57, 58 being shaped to. correspond to the shape of the-spring which has to be formed so that the member 57 working together with the member 58 (Fig. 8) produces the required shape for the spring. 9

The members 57 and 58 are actuated by the above mentioned cams 28 and 2921s also by the springs 59 and 60 respectively. While the cams 28 and 29 tend to push the members 57 and 58 into the positions shown in Fig. 7, the springs 59 and 60 tend to press the members 57 and 58 against the cams, thus tending to bring said members to their 5 original position.

7 an adjusta namely above the press-button 49 in with the two slots 50 in which the springs Fig.6, and the member v58 in that shown in b the nose of the end of the other Fig. 7, the wire is tient' member 58 into the ork member 57 so that the bending of the wire to form the 'spring 76 takes place between thetwo specially 'sh'aped ends of the members 57 and 58. If now the members 58, 57

again resume their original positions, the

rigid! ly or exchangeably connected to the table 56 or the part 62, spring from being bent away. he finished spring 76 which is still connected to the wire 39 is in the position shown in Fi 8!,

sto -pin 61) which is it is tobeinserted.

The tool for inserting the springs in the press-buttons consists o the stamps 64, 73. The strung) 64'is slidably mounted in a slide 65. in' sue a manner that it can yield backward. The slide is guided b a standard 66 arranged on the ta le 56. the table 56 are provided the openings 67 which correspond to the recesses 52 in the links 1 of the convayer chain. The stamp 64 which is subecte to the action of the spring 69 is limited in its stroke by the guiding pin 70 which in the stamp. At its lower end e stamp is provided with a cup-shaped ohollow 68, which is so dimensioned that, when the stamp travels downward it embraces the cap of the press-button either entirely or partly and in this manner resses the press-button against the table. he hollow 68 may be made so as to button, in which case, however, the ower edge of the stamp must rea h only as far as the slots 50, or said hollow 68 may be so made as not to correspond exactly to the ress-button eap, but may be higher than the atter. In this latter case, the hollow 68 has at its bottom edge a set-back at (Fig. 13) which corresponds exactly to the slot 50 of the ressbutton' ca and serves the'purpose of eepin' the pad? free for the spring to enter into t e slot 50 and guiding same into its place, when the stamp 73 is insorting the spring into the press-button. The stamp 73, which is also movably mounted in the slide 65 means of the screw-74, is at the same time constructed as a cutter, that is, it looks after y or resilientlyengages in the correspon ing slot 71 and vwhich is adjustable byrevents the exactly fit the cap of the ress- I the cutting oil of the spring fronrthe main wire well as the work of inserting the spring and the bending over of a portion of the .press button edge after the spring has been inserted in the pressbutton and cut oil from the main wire. For engaging the spring and cuttin it off from the main wire 39 and for bending the spring down this stamp is provided at the bottom with the notch 75 (Fig. 9). This notch has'a' sharp cutting edge which serves for cutting off the spring formed by the members 57 and 58 (F igs. 6 and 8) immediately before the insertion of the spring intothe press button takes place.

The slide 65 is pressed downwardly together with the stamps 64 and 73 by means main wire 39.

of thecam 4-7, until thebottom edge of the stamp 5-4 bears on the previously formed spring '75 which is still in one piece with the On the stamp 64'I1OW continuing its downward course the inner free end of the 5 nine 76 is deflected downward.

(dig. 1'3), the other end of the spring 76 still remaining attached to the wire 39, which is kept in place by the part 62. On

Y the stamp 6-1 traveling still farther downward, it embraces the press-button cap 72 and finally presses the pressbutton down on to the table 56 whereby the press-button is held immovably in its place. If now the slide 6: continues to ltrav elfarther down-' ward. the stamp 73 arrives by way of'the S1 in. the machine bed hit) the slot 52 of the conveyer frame. In 1) doing, the stamp '73 engages the spring 7 by means of notch 75, cats the spring at the edge (liie s. C 8) of the adjustable piece 62 from t e main wire, and when the slide arrives at the bottom of its stroke, bends over the edge clthe press-button at '7 9 (Figs. 12

and ll.5) to an extent equivalent to the breadth of the stamp 73, the inner end of the springj76 slips into the slot of the pressbutton cap '72, so that the spring is held securely in place by the bentover edge or the pressbutton and by the said slot 50 of the press-button cap. With the tool described'herein, a sure and exact insertion of springs into groups of press-buttons is attained, since, owing to' the fact that the springs are held by the wire 39 until they are completely inserted in the press-buttons, the

. springs are prevented from springing out or from being distorted in any way.

In Fig. 13 a modified form of construetion of the tool is shown in vertical sectionto a larger scale. This form differs from that just described only therein that' the stamp 73 is provided with a resiliently arranged part 80 which ispivotally mounted on a bolt 81 of the said stamp 73 and is so arranged that it; produces a side press 'e on the spring 76, while the latter is being inserted into the presy'button.

lVh'ez, the conveyer band made up of the frames or links 1 filled with press-buttons arrives at the tools for the formation "and the in-ertion'of the springs (Fig. 1), the springs are, according to the example now under consideration, formed and inserted on 0nd side of the press-buttons at the five points designated a, Z), a, (Z, e, the proced'ure being as follows :---The main shaft 7 first of all causes the wires 39 to be fed forward, then the members 57 and 58 to be brought into the positions shown'in Figs. 6 and -7 respectively, then removed from said positions and finally it causes the slide (Figs. 9-12) to be actuated. For this purpose the earns 37, 38 which c-flect the feeding forward of the wire 39 as also the cams 28 and 29 which actuate the members 57 and 58 and finally the cams 47 which actuate the slides 65 are all correspondingly displaced .With relation to one another. As soon as the wires 39 have b .1 fed forward, and the springs 76 have been formed and inserted-in the press-buttons at the working points a to e, the crank pin '11 of the crank arm 10 again engages one of the slots 6 of the star- Wheel 5 and revolves the, star-wheel, one

forward a'corresponding distance whereby any press-buttons which are not yet pro} vided with springs are brought to the working positions a to e.

By the apparatus shown in Figs. Land 2, the press-buttons are of course provided with springs only on one side. The apparatus which serves for producing and insert: ing the springs .on the other side of the pressbuttons can of course be arranged in exactly the same manner, b-ubwith the difference that the wires 39 are d in from the opposite side to that'shown in Fig.1 and that the slidably mounted members 57 and 58 are correspondingly changed about, and the stamp 73 is'arrangedon the opposite side of the stamp 64. I 3 As shown diagrammatically in Fig. 18,, the press-buttons which have been stamped out by means of known machines are laid in by hand or by mechanical means in the open-. lugs 51 of the links or frames forming the conveyer-chain, at. I. On the conveyor being moved forward they then arrive at the tools which, as above described, produce and insert the springs in the press-buttons.
